Template:BadJPEG

All images in this template were uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG format or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. For more information, see {{BadJPEG}}.

The template automatically sets the following categories: Category:Images with inappropriate JPEG compression, a subcategory of Category:Images for cleanup, if the filename ends in .jpg or .jpeg (if it doesn't, it categorises into Category:Files incorrectly marked as BadJPEG).

Usage

• 

  PNG: although it comes from the JPG source it has lesser file size (62 KB – could be better if a vector source, the darker hue is not that relevant here)
